SERVER, POWER MANAGEMENT SYSTEM, POWER MANAGEMENT METHOD, AND PROGRAM

摘要

To increase the reliability of power supply control of a server group and reduce the power consumption of the server group. A server includes a power supply stop control unit which stops a power supply of a predetermined processing unit upon receiving a power supply stop instruction signal instructing to stop the power supply, a power supply start-up control unit which intermittently starts up the power supply of the predetermined processing unit when the power supply stop control unit stops the power supply of the predetermined processing unit, a power supply start-up determination unit which determines whether a processing load of other servers which are executing their processes among a plurality of other servers is higher than an upper limit load determined in advance as a load required to be processed by servers the number of which is greater than or equal to the number of the other servers which are executing their processes when the power supply start-up control unit starts up the power supply of the predetermined processing unit, and a process control unit which controls process execution for the predetermined processing unit when the processing load of the other servers which are executing their processes is determined to be higher than the upper limit load.
